Vue.js: can't orderBy in v-for

Question

I've upgraded to Vue.js 2.0.5 and orderBy in a v-for seems to not be working anymore

<li v-for="c in rooms | orderBy 'last_iteraction'">

outputs

• invalid expression: v-for="c in rooms | orderBy 'last_iteraction'"

anyone knows how to solve?

Answer 1

orderBy Filter is removed in vue.js v-2.

Quoted from vue.js docs

Instead of:

<p v-for="user in users | orderBy 'name'">{{ user.name }}</p>

Use lodash’s orderBy (or possibly sortBy) in a computed property:

<p v-for="user in orderedUsers">{{ user.name }}</p>

computed: {
  orderedUsers: function () {
    return _.orderBy(this.users, 'name')
  }
}

Answer 2

You can also use vue2 filters package.

1) First install it using npm.

npm install vue2-filters

2) Then, add it in your component or globally.

import Vue from 'vue'
import Vue2Filters from 'vue2-filters'

Vue.use(Vue2Filters)

3) After that use it in the template

<li v-for="c in orderBy(rooms,'last_iteraction')"> 

There is a list of predefined filters.check it out.
